I think the current wall of text about help posts belonging in /r/AppleHelp is rely simple to ignore, because it is too much text, just as the wall of text above all new posts that nobody reads. Since the gray text in the input box is almost the same as the black text on top of the new post page, I think it should be replaced for something much more direct and simple: something like "Go to /r/AppleHelp if you need help or have a question", in big font. That would be much more difficult to avoid as it would get the attention of people.
